parents, marriages and children
- father Sigurd Snake-in-the-Eye (Sigurd Ragnarsson) · mid 9th century–0887? (traditional; possibly the Sigfred killed in West Francia 887) — disputed — inspect
- mother Blaeja of Northumbria · 9th century (traditional) — overlay — tradition-carried
Children listed here may not be the complete family — this edition follows the founder's blood line; siblings, other marriages and descendants largely live beyond the published record (coverage, not contradiction).
sources and research notes
era ≠ support: “—” dates the evidence; “unsourced-entry” assesses it — one never derives the other. Attribution distinguishes, never ranks.
- attested overlay — outside the provider walk; enters the record by evidence pack; class never rises above what its sources carry
- tradition — saga — not in the walked FamilySearch record — enters ONLY via this evidence pack and the attested overlay
- Semi-legendary Viking warrior and Danish king, mid-to-late 9th century; might have been the Danish King Sigfred who ruled briefly in the 870s. — Wikipedia (tertiary index) · source — opens a new tab
- Son of Ragnar Lodbrok and Aslaug; born with a mark in his left eye described as the image of the ouroboros — hence the name. — Wikipedia · source — opens a new tab
- Sources carrying him: Ragnarssona þáttr (Tale of Ragnar's Sons), Ragnars saga Loðbrókar, Saxo Grammaticus; Adam of Bremen names Hardegon's father as 'Sven' — a CONFLICT retained, not smoothed; Frankish annals place Sigfred/Halfdan ruling 873. — Wikipedia source survey · source — opens a new tab
- On hearing of Ragnar's death in Ælla's snake pit, he cut himself to the bone with a knife; joined the Great Heathen Army (865–866); York taken, Ælla executed by blood eagle under Ivar's strategy. — Wikipedia · source — opens a new tab
- Inherited Zealand, Scania, Halland, the Danish islands, and Viken; possibly co-ruled Denmark with Halfdan (~873), sole king ~877 after Halfdan's death. — Wikipedia · source — opens a new tab
- Married Blaeja, daughter of King Ælla of Northumbria (the king who killed his father). Children: Harthacanute (king of part of Denmark ~916; father of Gorm the Old; grandfather of Harald Bluetooth; ancestor of Sweyn Forkbeard, Cnut the Great, and every Danish monarch after 1047 via Estrid); Áslaug Sigurðardóttir (m. Helge of the Dagling line; their son Sigurd Hart's daughter Ragnhild connects to Norwegian royal genealogies). — Wikipedia · source — opens a new tab
- DEATH: no medieval source has Ivar the Boneless killing him — that scene is a television invention (Vikings S4E20). A landless Viking king named Sigfred, 'quite possibly the same person', was killed in West Francia in 887. — Wikipedia + Vikings Wiki (for the invented scene) · source — opens a new tab
